MicroSD Card - SanDisk Ultra 64 GB XC I Class 10

I formatted the card on my Windows 7 pc with FAT32. It is recognised by the phone and I can use it normally. But every time phone battery dies, I get the message that the SD card is blank. It gives me an option to format the card. I get the message - Erasing the card. The card is then usable. Its file system is listed as Generic hierarchical. It has Used Space 76.0 KB and Free Space 59.3 GB. It also has 2 directories - Android and LOST.DIR.

This has happened about 3 times now and results in losing all files on SD Card. Has anyone else experienced this and any opinions as to what can be causing this?

Thanks, demolition23. It would still be interesting to know if this is just an odd issue with my phone and sdcard OR has anyone else has experienced this particular problem. Could it be because 64 GB sd card is not officially supported?
